The software creates virtual scenes for participants to experience the authentic high-altitude environment. The experience system is mainly composed of emulation operation input system, machinery dynamic model, virtual emulation environment model, motion emulation system, real-time operating system, scene management system, vision and sound rendering output system, and model library.
Person re-identification, aiming to match a specific person among non-overlapping cameras, has attracted plenty of attention in recent years. It can be regarded as a visual retrieval task, namely given a query person image, ranking all gallery images according to their similarities to the query. Conventionally, this similarity function is learnt by forcing intra-distances to be small while inter-distances...
In this paper, we present an monocular vision-based autonomous navigation system for a commercial quadcoptor. The quadcoptor communicates with a ground-based laptop via wireless connection. The video stream of the front camera on the drone and the navigation data measured on-board are sent to the ground station and then processed by a vision-based SLAM system. In order to handle motion blur and frame...
Direct3D is used to set up the visual system of indoor track cycling simulator. The modeling, the world transformation, the view transformation and the projection transformation for rendering the scene are studied. The method to locate the cyclist can be simplified by dividing the track into two parts. One is the straight, the other is the bend. The three transformations are enough for the scene simulation...
